alerts summer-winter-time problem

Every day we have an alert at 2PM, now with the time change, the alert is sent at 1PM. What is the solution for this?

I found a solution on this site:
http://technet.microsoft.com/en-us/library/cc508847.aspx

But the they use this:

Invoke-AlertFixup -site <NewURL> -oldurl <OldURL>

But I don't have a New- and OldURL... The url is the same.

Does someone have a solution for this?
